View Command History
The command-history trace feature captures all commands entered by all users of the system with a time
stamp and writes these messages to a dedicated trace log buffer.
The system generates a trace message for each executed command. No password information is saved
to the file.
To view the command-history trace, use the
show command-history
command.
Example of the
show command-history
Command
Dell#show command-history

Upgrading Dell Networking OS
NOTE: To upgrade Dell Networking Operating System (OS), refer to the Release Notes for the
version you want to load on the system.
Using HTTP for File Transfers
Stating with Release 9.3(0.1), you can use HTTP to copy files or configuration details to a remote server.
Use the copy source-file-url http://host[:port]/file-path command to transfer files to an external server.
Enter the following source-file-url keywords and information:
• To copy a file from the internal FLASH, enter flash:// followed by the filename.
• To copy the running configuration, enter the keyword running-config.
• To copy the startup configuration, enter the keyword startup-config.
• To copy a file on the external FLASH, enter usbflash:// followed by the filename.
Using Hashes to Validate Software Images
You can use the MD5 message-digest algorithm or SHA256 Secure Hash Algorithm to validate the
software image on the flash drive, after the image has been transferred to the system, but before the
image has been installed. The validation calculates a hash value of the downloaded image file on system’s
flash drive, and
, optionally , compares it to a Dell Networking published hash for that file.
The MD5 or SHA256 hash provides a method of validating that you have downloaded the original
software. Calculating the hash on the local image file, and comparing the result to the hash published for
that file on iSupport, provides a high level of confidence that the local copy is exactly the same as the
published software image. This validation procedure, and the
verify { md5 | sha256 } command to support
it, can prevent the installation of corrupted or modified images.
